Application filed May 28,

timore, in the State of Maryland, have in vented certain new and useful Improvements in Washing Machines; and I do hereby declare the following to be a full, clear, and.

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to washing machines.

Among the Objects of my invention are To produce a washing machine in which the articles being washed will be subjected to practically the same kneading action as it they were washed upon an ordinary washboard.

To produce a washing machine in which the kneading action upon the articles to be washed shall be eficient tor the purpose of washing the articles but shall be carried on in such a manner as to preclude any possibility of injury to the articles.

To produce a washing machine and a supporting stand therefor mutually arranged so that the latter may be folded and placed inside the former when theoperation of washing is cdmpleted.

To produce a container for a washing machine and a supporting stand therefor so that the former may be readily removed from the latter and placed upon a stove or other source of heat, thus enabling the container to be used as a boiler.

To produce a' simple, cheap and etlicient washing machine especially suitable for Hull till

washing small batches of articles.-

Tn carryingout my invention ll make use of the instrumentalities illustrated in the accompanying drawings, in which;

F1 ure 1 is a side view of my improved washing machine.

Fig. 2 is aview of the washing machine shown in Fig. 1 looking in the direction of the arrow 2 in said figure.

Fig. 3 is a partial central section of the container showing the means for making a water-tight joint around the top of the con-" tainer and the lid.

Fi 4 is acentral section of the container showing the stand for supporting the 'container folded and the handle for turning the container, both storedwithin the latter.

the arrow 5 in said figure. The screws'36 and wing nuts 38 are omitted tor clearness.

In the drawings represents the container which may be of any approved shape and size. The container 10 has the top 11, bottom 12 and conjoining wall 13.

In the drawings, the top and bottom are shown square and the wall 18 isshown corrugated, but it is to be understood that the top and bottom may be of any shape and the wall 13 maybe smooth or provided with anydesired form of rough surface. However, T prefer to use the container made as'shown in the drawings as T find that'such a form gives highly satisfactory results.

The'top 11 is provided with the U-shaped flange '14- and packing 15 is introduced within the limbs of the U. Therev may be any number of pins such as 16 extending across the limbs of the U. The lid 17 is provided with a flange 18 which extends down between the limbs of the U and said flange is pro vided with obliquely disposed slots 19, equal in number to the number of pins 16.

When the flange 18 is introduced between the limbs of the flange ld'the lid is to be turned by the handles 20-20 until the slots 19 embrace the pins 16 and further turning forces the endot the flange 18 against the packing '15, thus forming a water-tight joint. The pins 16 and slots 19 together form sub- 'stantially a bayonet joint.

The brackets 21 and 22 are secured upon diagonally opposite corners of the wall 13,

the former being secured near the top 11 and the latter being secured near the bottom 12. The former supports the hollow pintle 23 and the bracket 22 supports the pintle portion 24 of the handle 25.

The pintle portion 2A fits snugly within a hole provided in the bracket .22 and a pin 26 passing through said bracket and the pintill til

tle portion 24 serves to removably secure the handle to the container 10 so that the former may turn the latter.

It is to be noted that the pintle 21 and the pintle portion 24 are in line and are so disposed with reference to the container 10 that the axis of revolution about which the latter turns is obliquely disposed to the conjoining wall and that it does not pass through the top or bottom of the container. By this construction, I am enabled to obtain a greater displacement of the articles within the container during each revolution than if said axis passed through the unctions of the top and bottom with the conjoining wall.

As another advantage of this construction,

the'bracket 22 is above the lower surface of the bottom 12; hence, the container may set flat upon a stove or other source of heat and the container can be used asa boiler,.the steam passing through the hollowpintle 23.

My improved stand for supporting the container 10. consists of a pair of legs 27 27 joined together by the pin 28 and each leg is provided with a hole 29 adjacent to the pin 28, the holes in the two legs being ini the angle iron as shown in Saidfigure, thus preventing the bottoms of said legs from .moving further apart than shown therein.

. A similar pair of legs 31- 31 is joined together by the pin 32 and otherwise made the same as the legs 2727 so that the holes 33-33 therein may serve as bearings for the pintle portion 2 10f the handle 25.

Trusses 34-34 formed of angle irons are hinged to the legs 27-27 and one of the limbs of each of saidangle irons is cut as at 35 so that said cut-away portion will rest againstthe leg 27 when the parts are in the positions shown in Fig. 1, thus preventing the right hand end of said trusses from moving below the position shown in said figure.

A screw such as 36 is secured in each of the trusses 34 and said screws are passed loosely through holes in the trusses 37-37 and wing nuts such, as 38 secure the ends-of said trusses together. 4 The trusses 37-37- are formed similarly to the trusses 34- -34;

The pintle 23 is made hollow so that the steam that may be evolved during the washin operation may escape therethrough. In order to preventthe'water which occasionally accompanies said. steam from splashing upon surrounding objects, I secure the drip cup 39 upon one of the legs 27 and provide the inner wall of said cup with a hole through which the left end of the hollow. pintle 23, (see Fig. ljl projects. into the interior of said cup. he cup '39 is come pletely enclosed excepting for the hole through which the pintle 23 projects and the hole .0 in the top of said cup. The hole 40 is for the purpose of draining said cup after the operation of washing is completed.

' When the pintlev 23 and the pintle portion 24 are introduced within the holes 29-29 and 33-33 they prevent the corresponding legs from being folded together.

The manner of use of my improved washing machine is as follows s The articles to be washed are to be introduced Within the container 10 and the lid 17 secured in place.

The pintle 23 is then introduced within the holes 29, the pintle portion 24 is passed through the holes 33 into the holein the bracket 22 and then the pin 26 is passed [through the hole in said bracket and the hole in said pintle. The handle 25 is then to be revolved and during the revolution of said handle, the articles within the container are moved upwardly and then. dropped downwardly, and during the upward and downward motion said articles are kneaded against the corrugations 0f the wall 13 and furthermore, are splashed into and through the liquid within the container, thus ensuring a thorough kneading of the articles and an intimate penetration and saponification of the same/by the water and cleansing compounds wit-hinthe container.

After the han'dlev has been turned for a suflicient length of, time, said handle is to be removed and the container is to be removed from its supportingstand and the bottom 12 the wing nuts 38- 38 are removed, thev trusses 37 are'separated from the trusses 34 and then folded upon the legs 31 and 27 respectivelygsaid legsare then to be folded together and the legs, trusses andthe handle are th'en to be introduced taineras shown in Fig. 4:.

While I have shown my improved washing machine as arranged for-washing small batches of articles, it is to-be understood that it may be of any desired size and may be provi ed with any approved filling and emptying devices.-

Furthermore, while I have shown one embodiment of my invention, it is to be understood that many changes may be made there in without departing from the spirit thereof.

I claim 1..The combination with a container for washing machines comprising a bottom, a top, a"conjoining Wall, said top having an opening to provide access to the interior of said container, of a pintle and, a pintle socket for revolubly supporting said container, said pintle being secured to said wall near said top and said socket being secured vide access to the interior of said container,

within the conanse a pintle secured to said container adjacent said top and having ahole therethr'ough to provide a ventto the interior of said container, and a pintle socket secured to saidcontainer adjacent said bottom in alinement' with said pintle and wholly above the plane of said bottom.

3. The combination with a container having a pair of aligned pintles, of a stand for supporting said container, said stand comprising two pairs of folding legs, a pivot joining the legs of each pair together, a bearing in each leg, the bearings in the four legs being in alignment-when said legs are unfolded for use, whereby when each of said pintles is introduced within the bearings of one pair of legs, said legs are locked in the unfolded position.

4. The combination with a container comprising an opening, a removable lid therefor and pmtles secured thereto, of a stand for supporting said pintles, said stand compris ing folding legs and folding trusses joining sa1d legs together in pairs, said trusses and legs when folded together being circumscribed within such limits that they will pass through said opening and of such lengths that said lid may be secured to said container when said legs and trusses are therein.

In testimony whereof, I afiix my signature.
